Phase Identifier Report approval

Dear Colleagues,

Some time ago I circulated a draft of the final report of the Working 
Group on a Crystallographic Phase Idenfier which everyone signed on to, 
though Vicky Karen, after consultation with her colleagues, came back 
with some suggestions relating to the Parthe-Gelato method of 
normalizing the Wyckoff sequence.  In repsonse to these comments, I 
modified the text to make it clear that Parthe and Gelato's non-stndard 
choice of the unit cell did not affect the proposed identifier other 
than ensuring a reproduceable Wyckoff sequence.  That is, the only 
change that was needed to the report was in the descriptive text, not in 
the structure of the identifier itself.  Since circulating the new 
wording, five of our members have indicated their approval, and since 
all the other members signed off on the earlier draft, I am assuming 
that they also approve of the current version.  Unless I receive any 
objections during the next seven days, I will forward the report to the 
Chair of the Commission on Crystallographic Nomenclature over the names 
of all members of the Working Group as our final report.  The report 
will then be circulated to the Commission members for comment and 
approval, after which (if it is not returned to us for correction) it 
will be published in Acta Cryst. and on the IUCr web site.

Best wishes

David Brown
